Along with the confirmed planet signals with 0.85 day and 3.69 day orbital periods, a third signal with a period of 8.96 days and an amplitude of \(\sim \) 4 ms\(^{-1}\)  also appears in all shift-driven periodograms, with no significant counter-part in the shape-driven periodogram as seen from Figure REF . This signal, noted previously by [1]} as being attributable to a third planet CoRoT-7d, was suppressed in the GP regression analysis of [2]}, attributing it to be more likely an activity signal. However, we found no significant signal at 8.96 days period in the activity-induced shape-driven periodogram, despite the dataset chosen. This argues against an activity-related origin.
